SPRING DRAFT ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 479,681, dated July 26,1892.

Application filed February 9, 1892, Serial No. 420,823. (No model.)

To all whom it may concern: bolts 15, extending through the bow and Beit known that 1, JOHN F. TINER, of Labraces, and these lugs arepivotally coupled vernia, in the county of Wilson and State of to theterminal eyes 16 at the rear ends of Texas, have invented a new andImproved the draw-bar frames 17. These frames 17 are Spring DrawingAttachment for Vehicles, of open on top and bottom and are elongated,which the following is a full, clear, and exact as shown in thedrawings, the frames having description. near the center thecross-pieces 18, which Myinvention relates to improvements in formabutments for the collars and nuts of drawing attachments for vehicles;and its obthe draw-bars, as described below. to ject is to do away withthe ordinary double- In each frame 17 is a draw-bar 19, which extree andprovide a simple spring attachment, tends longitudinally through thegreater porwhich may be secured to any vehicle, which tion of the frameand projects through the may be used for a one-horse vehicle, but frontend of the same, and the rear end of the which is especially adapted fora two-horse draw-baris screw-threaded and provided with I 5 vehicle,which when used on the latter vehia nut 20, which by striking thecross-piece 18 cle prevents the horses from pulling against limits theforward movement of the draw-bar. one another, prevents the pole fromswaying The draw-bar has also a collar 21, which is sidewise, enablesthe vehicle to run easily and preferably square, as shown in Fig. 4, andwithout jerks, and which is also very much this collar is secured to thedraw-bar in front 20 easier for the horses, as the springs used in ofthe cross-piece 18, and by striking the connection with the attachmentabsorb the cross-piece it limits the backward movement sudden shocks andvibrations. of the draw-bar.

I00

The arms 27 are braced by the curved braces 31, which are pivoted on thebolt 29 on the under side of the pole 10, and the outer ends of the armsare flattened, as shown at 32, and bolted firmly to the arms 27. Thebraces may thus swing in unison with the arms, and they will afford asecure support for the same. If desired, the top and bottom of the frame17 may be covered by a plate 33, thus forming a casein which thedraw-bar 19 and spring 22 may work.

It will be seen that the arms 27, while affording supports for thesinglctrees 26, will also serve as guides for the spring-frames 17 andthe draw-bars 19, and when the horses are secured to the singletrees itwill be seen that each horse will be practically independdent of theother, and that when either horse pulls the effect of the pull will beto draw the vehicle forward without throwing the pole sidewise, and itwill also be observed that the horses will be enabled to start withoutjerking the vehicle or without straining themselves, as the drawingstrain will first come on the springs 22, which will be compressed untilthe nuts 20 strike the cross-pieces 18 of the frame 17, after which theload will be carried in the usual way. It will be seen, too, that themoment a horse stops pulling the spring 22 will retract the draw-bar andthe singletree, so as to take the slack out of the traces and preventthem from being accidentally unhooked, and they will also prevent thehorses from getting their legs over the traces.

Having thus described my invention, I claim as new and desire to secureby Letters Patent '1. The combination, with a pole, of arms having theirinner ends pivoted to the pole,

singletrees pivoted on the outer ends of the arms, and an independentand yielding connection between each arm and the bow portion of thepole, substantially as described.

2. The combination, with the vehicle-pole, of oppositely-extending armspivoted thereon, singletrees pivoted on the outer ends of the arms,swinging open frames pivoted to a support in the rear of thesingletrees, and springrepressed draw-bars mounted in the frames andconnected with the singletrees and arms, substantially as described.

3. The combination, with the vehicle-pole, of swinging arms mountedthereon and extending on opposite sides the eof, curved braces connectedwith the arms and pivoted to the under side of the pole, singletrecscarried by the outer ends of the arms, open frames pivoted to a supportin the rear of the arms, spring-repressed draw-bars held to slide in theframes and connected with the singletrees and arms, and stops to limitthe movements of the draw-bars, substantially as described,

4. A spring drawing attachment for vehicles, consisting of a frameprovided with an eye at one end and with a cross-bar near its center, adraw-bar having one end screwthreaded and provided with an eye at itsother end and with a collar at its screwthreaded end, a nut on thedraw-bar, and a spring surrounding the drawar between one end of theframe and the collar of the drawber, substantially as herein shown andde-
